Simulation of multi-shell fullerenes using Machine-Learning Gaussian Approximation Potential

C. Ugwumadu et al.

Summary: This study simulated the formation process of multi-shell Fullerene buckyonions using a density-functional-theory (DFT)-trained machine-learning carbon potential within the Gaussian Approximation Potential (GAP) Framework. Fullerene clusters of seven different sizes were formed through self-organization and layering from the outermost shell to the innermost. The inter-shell cohesion is partially due to interaction between delocalized π electrons protruding into the gallery.

Coal polymer composites prepared by fused deposition modeling (FDM) 3D printing

Shuyang Zhang et al.

Summary: Coal is an important global energy resource, but the combustion of coal generates pollutants and greenhouse gases that harm the environment. In this study, anthracite and lignite were blended with polyamide 12 via FDM printing to produce composites, and their properties were compared. It was found that the addition of lignite improved the Young's modulus, while anthracite decreased the tensile performance. Rheology tests and morphology analyses suggested that the interactions between fillers and polyamide 12 played a role in the differences in tensile properties. Additionally, the printed lignite composites showed enhanced thermal conductivity, indicating their potential for functional composites. This research provides a strategy to utilize lignite in composites through 3D printing, creating value-added products and reducing the demand for petroleum-based polymers. Furthermore, this approach helps divert lignite from combustion processes and mitigate its negative impact on the environment.
